Has a poll been made before on this type of topic?

It might be worthwhile to see which brands the majority of users prefer. Obviously a seperate poll for I6's and V8's would be necessary.

I've done the test again.
And I definately have improved power in my I6 with Shell over the Ulimate98. It's also very slightly more smoother, tiny bit smoother on cold startup. Also sounds better at idle too.
